that is a good question i would say check with a frontend shop in your area see if you can find one that does trucks with a straight axle. maybe some one that does semi.s/ good luck it seems to me that the axle wold be to close to the frame if you put the springs under the axle.

I should have specified that I was talking about the rear! Sorry bout that! Anyway, after research, sounds like I'm giong to get a 5-6" drop flipping the rear axle on top of the leaf springs. Do appreciate it!
